The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "when fluid flows, there is some loss of energy due to friction." - This is true because as fluid flows, the layers of the fluid interact with each other, causing frictional forces. This friction leads to energy dissipation in the form of heat, which results in a loss of mechanical energy. 2. **Understanding the Reason**: - The reason states that "different layers of the fluid exert forces on each other." - This is also true. In a flowing fluid, adjacent layers move at different velocities due to viscosity, which is the measure of a fluid's resistance to deformation. The interaction between these layers creates shear forces, which are responsible for the friction mentioned in the assertion. 3. **Connecting Assertion and Reason**: - The reason explains why the assertion is true. The friction that leads to energy loss in a flowing fluid is a direct result of the forces exerted between different layers of the fluid. 4. **Conclusion**: - Since both the assertion and the reason are correct, and the reason provides an explanation for the assertion, we conclude that the answer is: - Both assertion and reason are correct, and the reason is valid in explaining the assertion. ### Final Answer: Both the assertion and reason are correct, and the reason explains the assertion. ---

Assertion : Angle of repose is equal to angle of limiting friction. Reason : When the body is just at the point of motion, the force of friction in this stage is called as limiting friction.

Assertion: If an object is submerged in fluid at rest, the fluid exerts a force on its surface. Reason: The force exerted by the fluid at rest has to be parallel to the surface in contact with it.

Assertion. When charges are shared between any two bodies, no charge is really lost but some loss of energy does occur. Reason. Some energy disappears in the from of heat, sparking etc.
